Utilized in medical applications, biodegradable materials based on magnesium have been widely explored throughout the years. It is well-known that alloying Mg with biocompatible and non-toxic elements increases the biodegradability of surgical alloys. The purpose of this study was to examine the microstructure and the electrochemical response (corrosion resistance) of a new experimental Mg-based biodegradable alloy\u2014Mg\u20130.5%Ca with additions of Zn as follows: 0.5, 1.5, and 3.0 wt.% in order to control the corrosion rate. Immersion tests were performed for different periods in a simulated body fluid electrolyte solution at 37 \u00b0C, and the mass loss was appreciated in order to calculate the corrosion rate (CR). The investigation led to the discovery of a dendritic Mg solid solution, a lamellar Mg2Ca compound, and a MgZn2 intermetallic phase. Scanning electron microscopy, optical microscopy, and energy dispersive spectroscopy were used for surface analysis after the immersion and electro-corrosion resistance tests. The metallic and ceramic compounds that detached themselves from the sample and passed into the solution were evaluated using the SEM-EDS system. All samples presented a generalized electro-corrosion with anodic and cathodic reactions of similar intensity. The corrosion rate was similar regardless of the percentage of zinc, with a smaller value for a higher than 3 wt.% Zn percentage based on the more protective zinc oxide that appeared on the surface.<\/jats:p>","DOI":"10.3390\/ma16062487","type":"journal-article","created":{"date-parts":[[2023,3,21]],"date-time":"2023-03-21T04:48:01Z","timestamp":1679374081000},"page":"2487","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":27,"title":["Microstructural and Electrochemical Influence of Zn in MgCaZn Biodegradable Alloys"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0817-3523","authenticated-orcid":false,"given":"Bogdan","family":"Istrate","sequence":"first","affiliation":[{"name":"Mechanical Engineering, Mechatronics and Robotics Department, Mechanical Engineering Faculty, \u201cGheorghe Asachi\u201d Technical University of Iasi, 700050 Iasi, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3878-9129","authenticated-orcid":false,"given":"Corneliu","family":"Munteanu","sequence":"additional","affiliation":[{"name":"Mechanical Engineering, Mechatronics and Robotics Department, Mechanical Engineering Faculty, \u201cGheorghe Asachi\u201d Technical University of Iasi, 700050 Iasi, Romania"},{"name":"Technical Sciences Academy of Romania, 26 Dacia Blvd., 030167 Bucharest, Romania"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5278-8958","authenticated-orcid":false,"given":"Mad\u0103lina-Simona","family":"B\u0103l\u021batu","sequence":"additional","affiliation":[{"name":"Department of Technologies and Equipments for Materials Processing, Faculty of Materials Science and Engineering, \u201cGheorghe Asachi\u201d Technical University of Iasi, Boulevard D.
